Initial analysis

This 12-unit, 3-story multi-family residential building at 1835 Noriega St in the Central Sunset neighborhood was built in 1962 and is currently owned by Nor Apartments. The property has undergone several significant improvements over the years, most notably completing a mandatory soft-story retrofit in 2015-2016 (with a $95,000 cost) that brought the building into compliance with San Francisco's seismic safety requirements. Recent building improvements include Ufer ground installation and various structural repairs, though several active building violations from 2016 remain unresolved, including issues related to lead hazards, carbon monoxide and smoke alarm requirements, and smoke enclosure door repairs. The building has experienced recurring maintenance issues over the years, with past complaints documenting problems such as water damage, mold, window framing issues, and various fire safety concerns.

Recent fire safety inspections have revealed both resolved and ongoing maintenance needs, including corrections made to sprinkler systems, exit maintenance, and fire extinguishers between 2021 and 2024. The property has a documented history of fire safety violations from 2001, which were subsequently abated, and earlier issues such as non-functioning intercoms and water damage from the 1990s. The building's infrastructure has received attention over the years, with projects including stucco replacement, reroofing, and various other repairs, though some older permits from 1996 remain expired in the records. Recent 311 calls for the area have primarily concerned external issues such as tree maintenance and sidewalk cleaning, while fire safety inspections continue to monitor building systems for compliance.

Risk rating

How 1835 Noriega St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
2th percentile

Out of 814 buildings in this neighborhood, 798 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 22.0%
Moderate concern 26.0%
Severe concern 52.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
